1. va: Let the backends optionally provide the absolute path for driver … …

   …loading
   
   - Split va_OpenDriver into va_OpenDriverFromPath and va_OpenDriverFromName
     to allow for absolute path driver loading and separate the dlopen logic
     from the possible paths calculation and iteration
   
   - Add new backend function vaGetDriverPathByIndex
     for driver candidate loading by absolute path
   
   - Rename va_getDriverNameByIndex to va_getDriverCandidateByIndex
     which will now get the driver name or path from the backend.
   
   - Rewrite va_openDriver which will now attempt to load the driver
     from the usual previous driver name and path construction process
     or use the new absolute path loading mechanism with or without
     LIBVA_DRIVERS_PATH env variable override.
   
   - Add extra attempt to load driver in va_OpenDriver
     without the drv_video suffix (win32 backend will need this)
     The two ways with/without suffix is for apps backward compatibility
